Benefits of technology

The invention solution allows for automatic synchronization of a switch between two subscriptions without any blocked or network connectivity issues. It requires no human intervention and does not require any additional memory space.

Problems solved by technology

It results that the terminal is in a blocked state when the two different subscriptions are not related to one and the same mobile radio-communication network.
Such a blocked state implies a loss of network connectivity which is disturbing for the terminal user.

Embodiment Construction

[0032]Herein under is considered a case in which the invention method for accessing a service is implemented by a mobile phone, as a first device and a chip host device, a remote server, as a second device, and a chip, as a third device, that is fixed to the phone.

[0033]According to another embodiment, the invention method for accessing a service is implemented by a mobile phone, as a first device and a standalone entity, and a remote server, as a second device. In other words, the phone, as a user terminal, does not cooperate with any chip, so as to synchronize, between a subscription manager supported by the phone and the phone OS, data relating to a subscription that is active after a subscription switch. According to such an embodiment (not represented), the first device is adapted to carry out the functions that are carried out by the chip and the first device and that are described infra.

[0034]Naturally, the herein below described embodiment is only for exemplifying purposes a...

Abstract

A first device stores a subscription manager and at least two subscriptions. A first subscription is active and a second subscription is non-active. A second device sends a request for switching to the second subscription. The subscription manager sets a first variable relating to a next active subscription to the second subscription. The subscription manager sends to the first device a message requesting the first device to re-launch an execution of the subscription manager and to read data. The first device sends to the subscription manager a message including a command for re-launching an execution of the subscription manager. The subscription manager de-activates, based upon the first variable value, the first subscription. The subscription manager activates, based upon the first variable value, the second subscription, and sends to the first device operating system data relating to the second subscription, as a current active subscription.

Description

FIELD OF THE INVENTION[0001]The invention relates generally to a method for accessing a service.[0002]Moreover, the invention pertains to a first device for accessing a service.[0003]The first device may be a terminal, like notably a mobile (tele)phone.[0004]The present invention is notably applicable to a mobile radio-communication field wherein a chip may be either an embedded chip, such as an embedded Universal Integrated Circuit Card (or eUICC) or a chip that is included within a smart card termed[0005]Subscribed Identity Module (or SIM) type card or the like, as a secure element.[0006]Within the present description, a Secure Element (or SE) is a smart object that, on the one hand, protects access to data that the smart object stores and, on the other hand, is intended to communicate with the outside world.STATE OF THE ART[0007]As known per se, a mobile phone, as a user terminal, cooperates with an SE, so as to identify and authenticate a subscriber to a mobile radio-communicati...
